HUAWEI ADSL2+ SHDSL VDSL2 DSLAM MA5616

Product Overview

The SmartAX MA5616 (the MA5616 for short) is an industry-leading remote multi dwelling unit (MDU) launched by Huawei, which supports flexible configurations and provides broadband services on Fiber To The Building (FTTB) and Fiber To The Curb (FTTC) networks. The MA5616 is a box-type device measuring 2-U high and 19-inch wide and providing two GPON or GE uplink ports and ADSL2+,VDSL2, SHDSL, POTS, ISDN, FE and GE ports. The MA5616 features a high access density, high processing capability, high reliability, easy maintenance, environment-friendlily and energy conservation, and future-oriented architecture design and can be used in corridors, cabinets, indoor, and outdoor usage scenarios.

Structure

The service boards supported by the MA5616 are as follows:

When the control board is CCUB, the MA5616 supports xDSL, ISDN, and POTS, and ADSL2+ and POTS COMBO service boards.

The configuration principles for the service boards are as follows:

Providing the POTS service boards that can be configured in all the four slots.

Providing the ISDN service boards that can be configured in all the four slots.

Providing the ADSL2+ service boards that can be configured in all the four slots.

Providing the ADSL2+ and POTS COMBO service boards that can be configured in all the four slots.

Providing the VDSL2 service boards that can be configured in all the four slots.

Providing the SHDSL service boards that can be configured in all the four slots.

2 Rich and Complete Specifications

The MA5616 provides multiple specifications. Carriers can choose the ideal one according to the user density, thus best balancing the input and output.

The MA5616 supports dual GE, and single GE + single GPON upstream transmission flexibly according to application scenarios and network construction modes. Port 1 on the MA5616 can be a GPON or GE optical port, and port 0 can only be a GE optical port. Users can configure upstream data on port 0 or a GE electrical port on the panel.

One-Site Deployment and Plug and Play

Offline deployment and plug and play (PnP) are supported. The hardware installation engineer can perform one-site deployment for the MA5616.

The MA5616 can automatically obtain the configuration data from the NMS and report information about MxU online to the NMS. The configuration data automatically takes effect.

Remote Batch Upgrading

The MA5616 supports automatic batch upgrading. After the upgrading policies are defined on the NMS, the NMS automatically upgrades network elements (NEs) in batches at a specified time.

The ONU can be upgraded using the OLT.

The MA5616 supports batch upgrading. When MA5616s are upgraded using the OLT, the upgrade efficiency is 6000MA5616s per five hours. When MA5616s are upgraded through the NMS, the upgrade efficiency is 800 MA5616s per five hours.

If the upgrading fails, automatic rollback is supported to restore the original version and data, thus ensuring the system security.

Boolean value monitoring (The Boolean values such as temperature, door status, and lightning can be monitored.)

Self-check and diagnosis of the device

LOS alarm and dying gasp alarm, identifying the disconnection of the ONU caused by broken optical fiber or power-off (Dying gasp: The system detects the output of the ONU power module. If the voltage drop is lower than the threshold, the system generates an alarm.)

Working with the N2510 (line assurance system launched by Huawei) to support intelligent diagnosis (The N2510 performs the intelligent diagnosis and sends the diagnosis result to the ONU, implementing automatic line optimization for the ONU.)

Network Performance Monitoring

Network optimization: The system monitors the traffic on the network side periodically. If traffic bottleneck occurs, the system adjusts the network resources and optimizes the network structure.

User monitoring: The system performs selective monitoring on the traffic of the user port to find abnormal traffic and invalid users.

4.High QoS

The MA5616 provides high quality of service (QoS) solutions to facilitate the management of different services.

T-CONT-based priority service in the upstream GPON transmission direction. Each service port has eight class of service (CoS) queues numbered from 0 to 7. Queue 7 has the highest priority and queue 0 has the lowest priority

Priority marking of the traffic-stream-based inner and outer VLAN tags

Protecting the power:In the AC + backup power configuration, the battery can be used as the backup power. When the AC power supply fails, the battery supplies power to the system. After the broadband service interruption feature is enabled, the broadband services are interrupted, and the narrowband services are normal.

DC: 3 kV in differential mode and 5 kV in common mode

AC: 6 kV

Controlling the fan. The speed of the fan can be adjusted intelligently. That is, the system can automatically adjust the fan rotating speed according to the working temperature, which has positive effect on reliable energy saving and noise reduction.

Replacing the fan tray independently.

Adopts the derating design for the electronic components to improve the reliability.

Provides the corrosion-proof design and reduces the cable routing on the board surface. A proper thermal design produces a temperature difference to prevent condensation.

Supporting H.248 dual homing. When the H.248 protocol is used, the MDU can be configured with up to two MGCs. When the MGC is switched over or the MDU detects the fault of the primary upstream link, the system automatically switches to the other MGC.

Supporting SIP dual homing. The MDU supports the 1+1 mutual assistance mode of the upstream P-CSCF/PROXY, that is, the deployment in the active/standby mode. When one of the upstream active/standby devices is faulty, the MDU service automatically switches to another device. Thus, the SIP disaster recovery scheme is implemented to improve the access reliability of the device.

Supporting the emergency standalone. When the MDU upstream port fails, the system automatically starts the emergency standalone function. Then, the subscribers of the same MDU can call and communicate with each other.

Supporting virtual noise. The system uses the virtual noise mechanism to decrease the line rate (the system adjusts the line rate according to the SNR), which improves the anti-interference capability of the system.

Software Design

The MA5616 supports the following functions:

Complying with the modularized and platform-based design concept, and adopts the loosely coupled design for each software module.

6.Strict Security

After deeply studying and applying security-related protocols, Huawei launches the MA5616 that meets the security requirements for telecom services and ensures the security of the system and the subscriber.

7.Perfect Voice Features

The MA5616 has built-in access gateway (AG) and inherits the platform capability and intercommunication capability of Huawei large-capacity AGs.

H.248/SIP

Up to 256 voice subscribers
